Water-elevator



UN STATES PATENT FFICE C. F. ANDERSON AND S. DAVIS, OF CLAREMONT, NEW HAMPSHIRE.

WATER-ELEVATOR.

Specification of Letters Patent No. 31,769, dated March 26, 1861.

l To all whom it may concern:

Be it known that we, C. F. ANDERSON and SYLVESTER Davis, both of Claremont, in the county of Sullivan and State of New Hampshire, have invented a new and Improved lVater-Elevating Device; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specication, in which- Figure l is a vertical section ofA our invention, taken in the line m, w, Fig. 2. Fig. 2 is a plan or top view of the same. Fig. 3 is a detached perspective view of a friction device pertaining to the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improved water-elevating device, designed for domestic purposes, and has for its object the ready elevation of the water and the discharging of the same automatically from the bucket; and also has for its object the gradual lowering of the bucket in such a manner that the same will be checked automatically and allowed to descend with a moderate speed, and the bucket thereby prevented from being injured.

The invention has further for its object the preventing of the accumulation of ice on the windlass or parts pertaining theretoa contingency which would prevent the proper action of the brake.

To enable those skilled in the art to fully understand and construct our invention we will proceed to describeit.

A represents a well-curb which ma'y be of the usual quadrilateral form, and B, is a windlass placed in the upper part of the curb. The windlass is formed of a shaft a, which is allowed a certain degree of longitudinal play or movement, one end of said shaft being fitted in a hub or boss o, on which a ratchet c, is placed, said ratchet having a pawl d, engaging with it. The hub or boss b, is fitted in one side of the curb B, and is allowed to turn freely therein, the inner end of the hub or boss being provided with a disk e, which is notched to receive an arm f, on the shaft a, when the shaft and hub are connected. The outer end of the hub or boss has aA crank C, attached to it.

On the shaft a, there are placed permanently two pulleys C, D. These pulleys are side by side and one of them C, has a metal strap E, attached to it. To the lower' endv of strap E, there is secured a bucket F, the

' bottom of which is provided with two valves g, L, both of which open upward. The valve g, is directly over a spout z', :as shown clearly in Fig. l, and said valve is provided with a curved arm or rod j, which extends above the top of the bucket F. The curb A, is provided with a spout G, at one side.

The pulley D, has a metal strap H, passing around it with a single coil or turn. This strap is attached at one end to the under side of a bar or lever I, and the opposite end of the strap is connected to a hook lc, which is at the inner end of a screw-rod J, which rod passes through the back of the curb and has a thumb nut K, upon it. To the under or inner side of the strap H, there is attached a leather strap L, which also passes around the pulley D. The strap L, is attached permanentlyto strap H, at one end as shown at Z, and the opposite end ofthe strap L, has a pin m, attached to it which pin is fitted in an oblong slot n, in the strap H, as shown clearly in Fig. 3.

To the front part of the bar or lever I, there is attached a hook M, and this hook fits over a plate N, at the front side ofthe curb, said plate being of curved form or having one part 0, projecting farther out than the other part p, as shown clearly in Fig. 2. The back end of the bar or lever I, projects through the back part of the curb A, and said bar or lever I, iits between the hanches g, g, of the pulley D, as shown clearly in Fig. 2.

In the upper part of the curb A, there is placed a partition O, one part of which is inclined as shown at r, the inclination corresponding or approximating to that of the upper curved part of the arm or rod j, of the valve g. In the back part of the curb A, there is made an opening h, as shown in Fig. 1.

The operation is as follows: In order to raise the bucket F, the crank C, is turned from left to right and t-he bar or lever I, is moved toward the hub or boss b, so that the arm f, will engage with the notches of the disk e, of hub b. This insures the rotation of shaft a, and its pulleys C, D, and the strap E, will be wound on the pulley C, and the bucket F, elevated.

proaches its culminating point the upper end of rod y', strikes the inclined part r, of the partition O, and the valve g, opens, allowing As the bucket ap` is loosened so as not to bind in the least around pulley D. This admits of the free rotation of shaft a. When the water has passed out of the bucket, the operator shove-s the bar or lever I, so that the hook M, will pass over the part 0', of the plate N, and in consequence of said part 0, extending` out farther from the curb than the part 29, the bar or lever I, will be drawn in the direction indicated by arrow 2, and the metal strap H, or rather the leather strap L, will bind on the periphery of pulley D, and produce sufficient friction to insure the easy or gradual descent of the bucket, the rotation of the pulley D, causing the metal strap H, to pull on rod J, which being unyielding of course does not diminish the friction produced by the strap L, on the pulley. This friction may be graduated as may be required by turning the thumb nut K, so as to adjust the rod J, farther in or out and thereby regulate the binding of the strap L, on pulley D. The leather strap L, insures a proper friction on pulley D, and by having one end of said strap fitted loosely to the metal strap H, the former is allowed to stretch and contractwithout affecting in the least its perfect op eration and without requiring any adjustment in consequence of said expansion and contraction.

When the bucket reaches the water in the well, the valve h, opens and the bucket fills, said valve 7L, of course closing when the bucket rises.

The partition O, prevents any moisture that rises from the well coming in contact with the windlass B, as a circulation of air passes through the spout Gr, and opening 7L', as indicated by the red arrows in Fig. l. This effectually prevents the windlass being clogged with ice-a Contingency which would materially affect the perfect operation of the machine.

In cases where a small portion of water is required to be drawn from the bucket the latter may, after being fully elevated and the requisite amount of water discharged, be lowered by raising the pawl d, from the ratchet c, and reversing the movement of the windlass so that the rod J, will be free from the inclined part i", of the partition O, and the pawl d, being theirengaged with the ratchet c, the bucket may be retained at the desired height until again raised to be further emptied. This it will be seen does not require the bar or lever I, to be manipulated.

IV e do not claim broadly the invention of a flexible brake that girdles or partially girdles the shaft upon which it acts; but

Having thus described our invention what we claim as new, and desire to secure by Letters Patent, is

l. Having the flexible girdling brake H attached to the shifting lever I, which operates the sliding windlass, B, when the said lever has both a lateral and longitudinal movement and when said parts are otherwise constructed, and arranged to operate with each other in the manner herein shown and described.

2. The arrangement of the adjusting hook J with the girdling strap in the manner herein shown and described.

3. The arrangement of the partition O, and rear aperture L, with the curb A, Windlass and brake in the manner and for the purposes herein shown and described.
